Photo-induced charge dynamics in 1-TaS
Francesco Petocchi, Jiyu Chen, Jiajun Li +2
Recent theoretical studies showed that the electronic structure of 1-TaS in the low-temperature commensurate charge density wave phase exhibits a nontrivial interplay betwee…
Time-resolved photoemission and RIXS study of a site-selective Mott insulator
Philipp Werner, Francesco Petocchi, Martin Eckstein
Inspired by the physics of rare earth nickelates, we study the photoemission (PES) and resonant inelastic X-ray scattering (RIXS) spectra of a correlated electron system with two t…
Dynamical mean-field study of a photon-mediated ferroelectric phase transition
Katharina Lenk, Jiajun Li, Philipp Werner +1
The interplay of light and matter gives rise to intriguing cooperative effects in quantum many-body systems. This is even true in thermal equilibrium, where the electromagnetic fie…
Stochastic semiclassical theory for non-equilibrium electron-phonon coupled systems
Antonio Picano, Francesco Grandi, Philipp Werner +1
We discuss a semiclassical approach to solve the quantum impurity model within non-equilibrium dynamical mean-field theory for electron-lattice models. The effect of electronic flu…
Sub-cycle multidimensional spectroscopy of strongly correlated materials
V. Valmispild, E. Gorelov, M. Eckstein +5
Strongly correlated solids are extremely complex and fascinating quantum systems, where new states continue to emerge, especially when interaction with light triggers interplay bet…
Control of Yu-Shiba-Rusinov States through a Bosonic Mode
Helene Müller, Martin Eckstein, Silvia Viola Kusminskiy
We investigate the impact of a bosonic degree of freedom on Yu-Shiba-Rusinov (YSR) states emerging from a magnetic impurity in a conventional superconductor. Starting from the Ande…
